我有两个单选按钮，可以启用/禁用wordpress主页中的特定类别帖子，

我还将这两个按钮添加到了single上。php，

这就是我所做的，

如果帖子属于“ABC”类别，且按钮处于启用状态，则显示以下消息：，

“请禁用按钮”（按钮就在此消息下方）

但当我选择禁用选项时，我会重定向到索引。php自动：它对分类页面非常有效，但对单个页面不起作用。php，为什么？

按钮代码，

<div id="filterbox">
    <form name="f1" method="POST" action="<?php echo $PHP_SELF;?>">
        <span>Family filter:</span>
        <ul>
        <li><input type="radio" name="r1" value="o" onClick="submit();" <?php echo (!$_SESSION[\'r1\'] || $_SESSION[\'r1\'] == "o") ? \'checked="checked"\' : \'\'; ?> />On</li>
        <li><input type="radio" name="r1" value="p" onClick="submit();" <?php echo ($_SESSION[\'r1\'] == "p") ? \'checked="checked"\' : \'\'; ?> />Off</li>
        </ul>
    </form>
</div>

这是类别内的代码。php，它工作正常，

<?php 

    if ( in_category($category) && $_SESSION[\'r1\'] == "o" ) { // See if the user is inside restricted category or if the Family filter is On (if one)
        echo "<div id=\'Naughtysms\'>";
        echo "Please turn Off the \'Family filter\' in order to read these SMS.<br /> these text messages are not suitable for user unders age 17";
        echo "</div>";
        echo "</div>";
    }
?>

这是单曲里面的代码。php，

<?php

            $currentCat = get_the_category();  // Get the Array of Categories of current Post
            $filterCategory = $currentCat[0]->cat_ID; // store the First category in filterCategory
            if (($filterCategory == $category) && ($_SESSION[\'r1\'] == "o" )){ // 
            ?>

please disable the button
<div id="filterbox">
    <form name="f1" method="POST" action="<?php echo $PHP_SELF;?>">
        <span>Family filter:</span>
        <ul>
        <li><input type="radio" name="r1" value="o" onClick="submit();" <?php echo (!$_SESSION[\'r1\'] || $_SESSION[\'r1\'] == "o") ? \'checked="checked"\' : \'\'; ?> />On</li>
        <li><input type="radio" name="r1" value="p" onClick="submit();" <?php echo ($_SESSION[\'r1\'] == "p") ? \'checked="checked"\' : \'\'; ?> />Off</li>
        </ul>
    </form>
</div>

这是他们每个人身上的代码，

$choice = $_POST[\'r1\'];
    $id = $category;
    if ($choice == \'o\') // Family Filter !!! If \'ON\'
        query_posts("cat=-.\'$id\'&".$query_string); // Remove Post from Category of particular ID
    else if (!$_SESSION[\'r1\'] || $_SESSION[\'r1\'] == "o") // If there is nothing in Session (opening page for the frst time) Remove the posts
        query_posts("cat=-.\'$id\'&".$query_string); 
    else {
        $_POST[\'r1\'] = \'p\';
    }

该代码用于索引。php/archieve。php，但不适用于单个。php（选择“禁用/关闭”后，我将重定向到索引，php。

echo $PHP_SELF;

 echo $_SERVER[\'PATH_INFO\'];
